INTRODUCTION In all over the world the use of concrete is increases day by day.therefore the uses of high strength and uses in high rise building and multistory building. Master Polyheed is a type of polycarboxylic ether and it is economical type.this product is developed for making application in ready mix concrete. It reduces the water and also maintains the set of retardation. it is free from chlorine and it contains low alkaline. it is good with all types of cement. This paper investigates the use of alccofine as partial replacement of PPC in M-40 and M-50 grade of concrete. The percentage replacement of PPC by alccofine was 0%, 5%, 10%, 15% and 20%. The test specimens (cubes) casted and tested as per relevant IS code of practice British code and American concrete institute method for 28 days compressive strength. II. LITERATURE REVIEW A. As per Siddharth P. Upadhyay Studied that the Compressive strength of high performance concrete with the replacement of cement with Alccofine and Fly ash, and also with natural sand to manufactured sand The concrete specimens were cured on normal moist curing under normal atmospheric temperature. The compressive strength was determined at 3, 7 and 28 days. The addition of Alccofine shows an early strength gaining property and that of Fly- ash shows long term strength. The ternary system that is Ordinary Portland cement-fly ash-alccofine concrete was found to increase the compressive strength of concrete on all ages when compared to concrete made with fly ash and Alccofine alone. B. As per Sharandeep Singh Studied that a comparison of DOE, ACI, BIS and USBR methods of concrete mix design, combining the test results of these methods.. M35 and M40 grades of concrete were used to carry out the comparison based on the mechanical properties of concrete. The observations showed that all the methods achieved the target mean strength either, in case of M40 or M35 except the ACI method in case of M40 for which the cement content has to be raised by an amount of 15 kg/m3, to fulfill the minimum requirements of compressive strength. Nevertheless, the USBR method attained the highest compressive strength either at 7 days or after 28 days, which was % of the target strength required. Whereas, the outcomes obtained by BIS and DOE method cannot be overlooked. The USBR method attained maximum flexure strength for M35 grade, whereas, BIS achieved highest values of flexure for M40 grade C. As per Saurabh Gupta 857

2 Studied that Effect on compressive strength of high performance concrete incorporating alccofine and fly ash the Compressive strength of high performance concrete with the replacement of cement with Alccofine and Fly ash, and also with natural sand to manufactured sand. The compressive strength was determined at 3, 7 and 28 days. The addition of Alccofine shows an early strength gaining property and that of Fly- ash shows long term strength. The ternary system that is Ordinary Portland cement-fly ash-alccofine concrete was found to increase the compressive strength of concrete on all age when compared to concrete made with fly ash and Alccofine alone. D. As per M.S. Pawar Studied that the comparison of the properties of self compacting concrete with fly ash and Alccofine to that of standard one. With fly ash The main variable is proportion of Alccofine keeping cement, fly ash, water, coarse aggregate, fine aggregate and super plasticizer contents constant The addition of Alccofine in SCC mixes increases the self compatibility characteristic like filling ability, passing ability and.resistance to segregation. Fresh Properties and harden Properties of SCCs with 10% Alccofine are superior than SCCs with 5% and 15% of Alccofine. E. As Per Deepa A. Sinha Concrete mix design is the process of choosing suitable ingredient of concrete and determining their relative quantities with the object of producing as economically as possible concrete of certain minimum properties, notable workability, strength and durability. It should be explained that an exact determination of mix proportions by means of table or computer data is generally not possible. The main objective of the study was to design M25 concrete mix and find the compressive strength using different mix design methods like IS , IS , ACI method and DOE method. We conclude that in above four methods minimum cement content used in DOE methods and it gives desire compressive strength of concrete economical way. III. EXPERIMENTAL INVESTIGATION A. Materials Cement In this experimental investigation Portland pozzolana cement was used. B. Fine Aggregates The fine aggregates used in this investigation was Natural River sand passing through 4.75 mm sieve with specific gravity of The percentage of passing is within the limits as Indian Standard Specification. The fine aggregate corresponds to the zone II gradation as per IS 383:1970. C. Coarse Aggregates Normal crushed broken stone aggregate angular in shape was used as coarse aggregates. Only one fraction of coarse aggregates were used, 20mm size having specific gravity of D. Alccofine Alccofine has unique properties to enhance the performance of concrete' in fresh and hardened stages due to its much finer particle size. Alccofine is manufactured by some controlled conditions with special technique to produce micro fine size. Alccofine is generally two types one is low calcium silicate which is Alccofine 1203 and other is high calcium silicate which is Alccofine E. Water Ordinary tape water clean, potable free from suspended particles and chemical substance was used for both mixing and curing of concrete. F. Master Polyheed 8632 Master polyheed is a type of polycarboxylic ether and it is economical type.this product is developed for making application in ready mix concrete. It reduces the water and also maintains the set of retardation. it is free from chlorine and it contains low alkaline. it is good with all types of cement. 858

4 respectively was adopted. IV. PREPARATION OF SPECIMENS The strength characteristics of concrete with varying percentage of alccofine were studied by casting cubes. The constituents of the concrete via, cement, fine aggregate and coarse aggregate were mixed to appropriate proportion by adding water Alccofine is added to the different mix in varying proportion as a partial replacement for cement. Moulds for cube of size 150 x 150 x 150mm were prepared and concrete was poured in to the mould layer by layer and compacted thoroughly. The specimens were removed from the moulds after 24 hours and then the specimens were cured with water for 28 days. V. RESULT AND DISCUSSIONS It was found from the experimental results that the compressive strength has increased for the specimens with varying percentage of alccofine as replacement for cement when compared with the conventional concrete at percentage of 10% after that adding of alccofine increases the strength decreases gradually. The optimal dosage at 10% gives the good strength.

CONCLUSIONS In this study series of the experiments have been conducted on concrete with the addition of alccofine as partial replacement of PPC. In the alccofine was used as partial replacement of PPC in different percentage that is 0%, 5%, 10%, 15% and 20% of the dry weight of the cement. The experiments were conducted on M-40 AND M50 grade of concrete as per relevant IS code of practice. Based on the test results obtained from this study the following conclusion can be drawn. A. According to these results Super Plasticizers, for high-strength concretes by decreasing the w/c ratio as a result of reducing the water content by 20 30%. B. ACI method gives max. Strength as comparison of IS method. C. By adding of alccofine at 0, 5, 10, 15, 20% at 10% gives optimal result and increases strength up to 10% and after 10% it addition strength decreases. D. The slump value is decreases by adding increase percentage of alccofine. E. ACI method gives higher quantity of fine aggregate which increases water demand and hence its affect the strength of HSC which is not acceptable.. F. ACI method gives more binder content with more proportion of fine aggregate, leading to reduced strength of the mix. G. In the ACI method the coarse aggregate content is constant for all grades of concrete, whereas in BS and IS methods it is variable.
